Remove or disable port-channel

You can delete or disable a port-channel.

1. Delete a port-channel in CONFIGURATION mode.

no interface port-channel channel-number

2. Disable a port-channel to place all interfaces within the port-channel operationally down in CONFIGURATION mode.

shutdown

Delete port-channel

OS10(config)# interface port-channel 10

OS10(conf-if-po-10)# no interface port-channel 10

Load balance traffic

You can use hashing to load balance traffic across the member interfaces of a port-channel. Load balancing uses source and

destination packet information to distribute traffic over multiple interfaces when transferring data to a destination.

For packets without an L3 header, OS10 automatically uses the load-balancing mac—selection destination-mac

command for hash algorithms by default.

When you configure an IP and MAC hashing scheme at the same time, the MAC hashing scheme takes precedence over the IP

hashing scheme.

● Select one or more methods of load balancing and replace the default IP 4-tuple method of balancing traffic over a

port-channel in CONFIGURATION mode.

OS10(config)# load-balancing

ingress-port Ingress port configurations

tcp-udp-selection TCP-UDP port for load-balancing configurations

ip-selection IPV4 load-balancing configurations

ipv6-selection IPV6 load-balancing configurations

mac-selection MAC load-balancing configurations

○ ingress-port [enable] — Enables the ingress port configuration. This option is not supported on S5148F-ON.

○ tcp-upd-selection [l4–destination-port | l4–source-port] — Uses the Layer 4 destination IP

address, or Layer 4 source IP address in the hash calculation. This option is not supported on S5148F-ON.

l4–source-port] — Uses the destination IP address, source IP address, protocol, VLAN ID, Layer 4 destination IP

address, or Layer 4 source IP address in the hash calculation.

○ ipv6-selection [destination-ip | source-ip | protocol | vlan-id | l4–destination-port

| l4–source-port] — Uses the destination IPv6 address, source IPv6 address, protocol, VLAN ID, Layer 4

destination IPv6 address, or Layer 4 source IPv6 address in the hash calculation.

○ mac—selection [destination-mac | source-mac] [ethertype | vlan-id] — Uses the destination

MAC address or source MAC address, and ethertype, or VLAN ID in the hash calculation.

Configure load balancing

OS10(config)# load-balancing ip-selection destination-ip source-ip

Change hash algorithm

The load-balancing command selects the hash criteria applied to load balancing of traffic on port-channels. If you do not

obtain even traffic distribution, use the hash-algorithm command to select the hash scheme for LAG. Rotate or shift the

L2-bit LAG hash until the desired traffic distribution is achieved.
